WebLearn from my experience with using Canny Edge Detection and ORB Feature Matching to detect objects in video games in real-time.Full OpenCV tutorial playlist... WebORB is found to be least scale invariant. ORB(1000), BRISK(1000), and AKAZE are more rotation invariant than others. ORB and BRISK are generally more invariant to affine changes as compared to others. SIFT, KAZE, AKAZE, and BRISK have higher accuracy for image rotations as compared to the rest.
WebThe similarity comparison has to be at least rotation invariant. Therfore I am using ORB features, and perform a one to one comparison of the descriptors using FlannBasedMatcher. This works fine so far. From what I have read on various sources on the web, I assume that I can also use Flann to make a one image vs. multiple images comparison.
